Abstract (en)
A method for estimating a property of a formation surrouning a borehole comprises applying transient well-test conditions to the borehole. A portion of the formation is excited with an acoustic signal. The acoustic response corresponding to the acoustic exciting is measured with an acoustic receiver located within the borehole. The property of the formation is estimated using the acoustic response.
